Controls
Maintain a Proper Sitting Position
After all occupants have adjusted their seats and head restraints, and put on their
seat belts, it is very important that they continue to sit upright, well back in their
seats, with their feet on the floor, until the vehicle is safely parked and the engine is
off.
Sitting improperly can increase the chance of injury during a crash. For example, if
an occupant slouches, lies down, turns si deways, sits forward, leans forward or
sideways, or puts one or both feet up, the chance of injury during a crash is greatly
increased.
In addition, an occupant who is out of position in the front seat can be seriously or
fatally injured in a crash by striking interior parts of the vehicle or being struck by an
inflating front airbag.1 Maintain a Proper Sitting Position
3WARNING
Sitting improperly or out of position can
result in serious injury or death in a crash.
Always sit upright, well back in the seat,
with your feet on the floor.
